When searching on Stack Overflow using the "answers:N" syntax, there appears to be a bug.
When you search for
answers:1, it returns ~360200 results.
When searching for
answers:2 it returns ~270300 results.
However, searching for
answers:0 returns ~18700 results.
Since the wording states that it will return questions with "N or more answers" the search for 0 should return more than searches for 1, not significantly less.
